A system and method are disclosed for removing a uterus using a fluid enclosure inserted in the peritoneal cavity of a patient so as to enclose the uterus. The fluid enclosure includes a distal open end surrounded by an adjustable loop, that can be tightened, a first proximal opening for inserting an electrosurgical instrument into the fluid enclosure, and a second proximal opening for inserting an endoscope. The loop is either a resilient band extending around the edge of the distal open end or a drawstring type of arrangement that can be tightened and released. The fluid enclosure is partially inserted into the peritoneal cavity of a patient in a deflated condition and then manipulated within the peritoneal cavity over the body and fundus of the uterus to the level of the uterocervical junction. The loop is tightened around the uterocervical junction, after which the enclosure is inflated using a conductive fluid. The loop forms a pressure seal against the uterocervical junction to contain the conductive fluid used to fill the fluid enclosure. Endoscopically inserted into the fluid enclosure is an electrosurgical instrument that is manipulated to vaporize and morcellate the fundus and body of the uterus. The fundus and body tissue that is vaporized and morcellated is then removed from the fluid enclosure through the shaft of the instrument, which includes a hollow interior that is connected to a suction pump The fundus and body are removed after the uterus has been disconnected from the tissue surrounding uterus.

The invention relates to the use of a thermal reversible gel, such as a copolymer composition, as a biological filler or implant. The gel has a semi-solid form at body temperature, but upon cooling to a temperature below a threshold level, the gel is liquefied and can be re-shaped, re-sized, manipulated or removed from the body. The gel may be used as a subcutaneous implant, a biological filler, joint or tissue spacer, for wrinkle filling or other cosmetic implants, as a soft-tissue replacement for reconstructive surgery, or as a barrier within the lumen of a biological structure, such as a blood vessel. The implant may be used to provide reversible birth control by providing, for example, a reversible barrier to the cervix or a reversible blockage of the lumen of the vas deferens.
